Logistic function

A logistic function or logistic curve is a common S-shaped curve (sigmoid curve) with equation

Think of it as exponential growth that starts running out of resources. In this pandemic's case, it's people to infect.

Exponential growth. Can some share a good natural example of something growing

embryonic cells peter out as fetus matures. Locusts haven't consumed the earth.

Every exponential growth eventually halts or is slowed.

Isn’t that why everything covid related talks in terms of a bell curve? It

could be a terrifying movie. The uninhibited exponential growth.

A good video why exponential growth is unsustainable in the real world

Exponential growth can be as little as .01%. It's the sustained nature.

I specified a doubling as exponential growth.

That's not what exponential growth means, though.

I know, but that's what social medial hobbyists are constantly pointing at.

R0 isn't an inherent feature of the virus. It depends on many factors.

And thus it illustrates the "power" of exponential growth.
